JEE Main Physics question
An ice cart of mass 60 kg rests on a horizontal snow patch with coefficient of static friction 1/3. Assuming there is no vertical acceleration, find the magnitude of the maximum horizontal force required to move the ice cart (g = 9.8 ms⁻²)
Answer: (D)
Solution
F = μmg = (1/3)(60)(9.8) = 196 N.
